` This invention relatesto the class of pastry making rand pertainsparticularly to` a machine design to facilitate the introduction` of creaminto 'puff pastries-or for the introductionof other iuidsor'semi-fluids'into'bodies `l of pastry.'

'The primary object offtheilpresent inve -V tion is to provide. a machine-by `means of whichmeasuredquantities of cream or paste v may be 'injected into pastry shellsor puffs by forcing these measured quantities at regular intervals-.through nozzles, theoutlet ends of which are'formed'to facilitate theirextension `into-the body of the pastry.

The invention broadly contemplates the provision of a receptacle havinglone or more pipes leading'therefromythrough ,a check -valve and -to av pipe opening at one end into gopaste or cream*A injecting nozzle, .a one-way valve being interposed'between the rear end of the nozzle yand the end of the pipe with which' the nozzle connects to preventl air from being sucked into the machine throughthe nozzle during a period in the operation ofthe machine. f v i '4 Reciprocably mounted in the cylinder is a piston member which is actuated by an os- .cillating arm carriedby an oscillatingoshaft, k which in turnv is actuated through asystem of shafts Vand connections by a suitable power Velement-suchas an electric motor. The operation of the motorcauses the pistonl to reciprocate at a regulated speed and at each idling stroke lthepiston draws paste fromthe re- 5 ceptacle through the firstA mentioned one-way vvalve andvupon the power strokeejects the paste through the second mentioned valve land through the nozzle into the pastry body 40 into which the outlet end of the nozzle has 'beenl extended. 1' f c :The invention will be best understood from a consideration of the following detailed description taken in connection with the accom- Vpanying drawings forming a part of this 'f 1,'this -framebeing preferably mounted upon the frame shown -will be described forthe specification, with the understanding, how- ,l ever, that the invention is not confined to any strict 'conformitygwith the vshowing of the -drawingszbut maybe changed or'modifiedso long assuch changes o r modifications Vmark no material departureffrom the salient feao .tures-oftheinvention as expressed in the appended claims.` l'

It is, kof course, to be understood that the frame structure shown is one form which may/be employed and I do not wish to be limited in'any manner to the use of a frame 7 5 vor'body structure-of this character, as it is p' obvious that other means may be employed for supporting themechanism hereinafter described.,V however,l the detailed structure ofk sake ofclearness in connection with the description of the mechanism which it carries. The frame ly comprises a baseportion 3 of generally rectangular formation, and uprights 4, one at each corner of the base, and a top frame 5 of similar construction to the base 3.

Mounted upon the base 3 is arpower unit,

preferably an electric motor 6, the shaft 7 of `which connects with a speed reducing mech- `9o meshed gears 9-and 10 with a horizontal shaft 11 rotatably supported between the spaced y upright members 12.

The shaft 11 carries at one end a crankl 13 to which is connected Van arm 14 designed to reciprocate vtransversely of the framestructure, in the manner shown. e

The end of thev arm 14, remote from the cranlr 13, carries a pin' 15 which is adjustably secured in the'slot 16 formed longitudinally in the lower end of arnormally vertically arranged rock arm 17traversedintermediate its ends by a rock shaft 18, the ends of 'which are .suitably mounted in the spaced upright members 19 carriedvupon the' base 3 of the frame. Suitable adjustable collarsY 2O are carried by the rock shaft 18,. at opposite sides of the rock arm to hold the same in adjusted position thereon. Y j v v The upper endof the rock arm 17 has pivotally secured thereto onegend of afsecond reciprocating `arm,which isY indicated by the'. numeral-21, the other end of this arm being pivotally secured to the lower end of -asecondV depending rock arm indicated by the' numeral 22, carried by a mainfrock shaft 23. .The

` arml 21 carries a pin 24, similar to the pin 15 carried by the arm 14, which pin is adjustably secured in a slot 25 formed longitudinally ofv thelow'er end of the roclt arm 22,' in the manner shown. 5

Any' suitable lmeans `may be vemployed for mounting the ends of the main rock shaft 23, as for example, there may be .provided at'each end of the shaft a hanging bearingmember 26 in which the. endof the shaft may position.v

`Mounted upon f the top portionl 5 of the frame structure in spaced substantially parallel vrelation is v:a pair Vof, piston cylinders, each of whichis indicated by the numeral 27. To the forward end of each ofthese cylinders 27,isconnectedbymeans of a nipple r28, one arm of a three-way coupling 29, the.; opposite arm of each coupling havingconnected thereto a vone-way outlet valve 30 to the opposite yside of'which valve vthe-base portion-of a tubular'needle or nozzle 31 is connected.v

c The third or lateral army of each three-way coupling connects with one sidev of anA -inlet j check valve 32, the oppositeside of which j valve isin communication withfthe Yinterior vof ay fluid receptacle 33 through the pipe line 3 Asshown, thepipe line 34 connecting the receptaclewith the one-way inlet valve 32 enters the receptacle through the bottom and assists in the `support thereof.

Extending intoeach of the cylinder`s-27 Vthrough the other. or rear ends thereof is a piston 35, having a rod 36 connected thereto,

VVea/ch'ofisaid rods-having pivotal connection as at 37, with one end of a connecting arm 38, .the other end of which arm is secured to the main rock shaft 23 to be rocked therewith.

the rocking of the shaft'23 'liquid receptacle,

From the description given it will be readily seen that in the use of the present machine, vwhen the motor '5 is started, the arms 17 and 22 will be rocked back and forth and cause and the arms 38 connected thereto.

The rocking of the arms 38 will cause reciprocatory movement of the pistons V35 and upon each backward movement of each piston, a predetermined quantity of the cream puff filling material will be sucked into the cylinders through the inlet-check valve 32 and upon the forward movement of each piston this lsame quantity of :material will be' ejected'through the one-way outlet valves 30 Vandvvthrough the nozzles or needle 31 into Y theypastry body into which the free end of the needle 31 has `been extended.

In any suitable position upon the upper portion of the frame 1, there may be mounted a control-switch. 39 for the motor, connection being madelbetween the switch and the current supply line forthe motorthrough the cabledvcurrent wire carrying line 40.

4 From the foregoing description itI will be readily seenthaty with a machine of thecharacter hereindescribed cream puffs and other articles Aof al similar' nature, may be morev rapidly lledthan by the employment of methods at present in use and further, exactly the same quantity of material will be ejected into :each body of pastry. It-is,-of course, obvious that by the adjustment of the connections between thereciprocating arms 14 and-251y andthe oscillating or rocking arms V17' and 22, the throw of the piston controlling arms 38A maybe increased or decreased to increasev or decrease the quantity of lmaterial ejected through the nozzles y31 and by the Yuse ofasuitable control rheostat-the speed fof .themotor' 6 may be regulated as desired.

VHaving'described my invention, what I -claim is v f LA machine for. injecting liquidsV intopastries, comprising a supporting frame, a pair of pumps mounted upon lthe frame and each including a cylinder and a piston, a liquid receptacle, a pipe line extending from one end of eachof `said cylinders, the axis 'of saidY pipe line being coplanar withv the axis; of said cylinder, a nozzle associated Vwith each pipe line,

a check valve interposed between each nozzle and the adjacent cylinder, alateral pipe line connecting each .of

the first mentioned pipes between the check Vand the cylinder with the receptacle, a check valve in each of said lateral pipes, and power operated lmeans for reciprocating leach of the pistons ofsaid pumps. f
